    Screen monitor desk top brightens or dulls if you bump or wiggle the connection cable


    my desk top Dell monitor brightens or dulls, its not a lot just a little, if you bump or wiggle the cable. I have unplugged it & reconnected 2 or 3 times or wiggle the cable connection till i get the brightest screen and seams to work OK for a while even weeks, but if i hit it or wiggle it again, it will still do the same. I have the feeling that the connection seams to need some kind of contact spray, is there a contact spray for computers like they use for electrical contacts ? ? thank you * Moved from Community Center
